[IMP] Allow the usage of the official odoo image with dokku PaaS

This commit allow us to directly push this repo over dokku mini-Paas
this has some drawback:
 - the Dockerfile should be in the project root, a symlink is used
   here to allow simple version swap
 - expose port should be changed to 8080 to get advantages by the nginx
   configuration system from dokku
